Unable to hide navigation bar that suddenly appear after popViewController in SearchDisplayCotroller

Question

I have a problem where a navigation bar suddenly appear after popViewController is called when SearchDisplayCotroller is still active.

I am implementing a simple tableview with searching capability. Above is my storyboard.

On the first view, i've implemented as per below. So, the navigation bar will be always hidden for the first view.

- (void) viewWillAppear:(BOOL)animated{
[self.navigationController setNavigationBarHidden:YES animated:NO];
}

Button press will push the next table view controller with the below code so that the navigation bar will be visible.

- (void) viewWillAppear:(BOOL)animated{
    [self.navigationController setNavigationBarHidden:NO animated:NO];
}

Everything works fine until i implemented the below code.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    [self.navigationController popViewControllerAnimated:YES];
} 

When popViewControllerAnimated:YES while the SearchDisplayController is still active, a weird white navigation bar appears and my viewWillAppear is unable to hide the bar. Is this a bug or is there any way to prevent this bar from appearing?

The gif below may also give you the idea what did happen. Thanks!

Answer 1

Try this

-(void) viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:animated];
  // To check if searchDisplayController still active
  if ([searchDisplayController isActive]) {
    [searchDisplayController setActive:NO];
  }
}

Try inactivating your UISearchDisplayController by calling setActive:NO animated:NO before you call [self.navigationController popViewControllerAnimated:YES];
